BURLINGTON, VERMONT (July 21, 2025) \u2014&nbsp;<\/strong>Hartzell Propeller has received FAA Part 35 Type Certification for the first propeller designed specifically for advanced air mobility (AAM) aircraft. The company worked with aerospace company BETA Technologies to achieve this landmark, conducting all testing of its propeller on BETA\u2019s proprietary electric propulsion systems (electric engines), which are designed and manufactured in-house by BETA.<\/p>\n\n\n\n<p>This milestone signifies the maturity, certifiability, and commercialization of the AAM industry, and next-generation electric aviation. It is also a huge practical step forward in the industry\u2019s collective ability to support the growing demand for safe, low-cost, and efficient urban and regional air transport.<\/p>\n\n\n\n<p>With this certification, Hartzell\u2019s propeller is the first to earn FAA type certification specifically for integration with electric propulsion systems. These systems, like BETA\u2019s, are capable of managing a wide range of different loads and conditions \u2014 from regenerative braking to startup \u2014 all of which Hartzell\u2019s propellers are uniquely designed to support. The approval comes after thousands of hours of ground and flight testing over four years, and verifies that the propeller exceeds the rigorous performance and safety standards of FAA Part 35.<\/p>\n\n\n\n<p>This is a critical endorsement from the FAA of the efficacy and safety of Hartzell\u2019s propeller \u2014&nbsp;as well as the performance of BETA\u2019s electric engines, which provided the foundation for its testing.<\/p>\n\n\n\n<p>\u201cHartzell Propeller is very pleased to work with BETA Technologies on this AAM breakthrough development,\u201d said Hartzell President JJ Frigge. \u201cOur design specifically for BETA Technologies is a five bladed, carbon fiber, ground adjustable fixed pitch propeller that will have future applications for the entire AAM industry.\u201d<\/p>\n\n\n\n<p>Hartzell and BETA have worked on the propeller development since 2021, from initial aerodynamic modeling and design to full-scale testing and validation. The result is a high-performance, low-noise propeller tailored specifically for electric engines and this next generation of aviation. BETA will utilize Hartzell\u2019s propeller to optimize the performance and safety profile of both its ALIA VTOL and ALIA CTOL aircraft. The propeller is also built to serve all AAM aircraft that utilize similar electric propulsion systems.<\/p>\n\n\n\n<p>\u201cWith its decades of experience across all types of aircraft, Hartzell Propeller has understood from the beginning the unique challenges and opportunities of electric aviation,\u201d<strong>\u00a0said Kyle Clark, Founder and CEO of BETA Technologies<\/strong>. \u201cTheir engineering precision and deep certification experience have assisted us as we bring this aircraft to market and walk through our own certification steps. We\u2019re proud to have been their counterpart on this project, and look forward to getting this certified propeller in the air as we continue the process of certifying our electric engines, as well as our ALIA CTOL and VTOL.\u201d<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"642\" src=\"https:\/\/hartzellprop.com\/wp-content\/uploads\/unnamed-16-1024x642.jpg\" alt=\"\" class=\"wp-image-27232\" srcset=\"https:\/\/hartzellprop.com\/wp-content\/uploads\/unnamed-16-1024x642.jpg 1024w, https:\/\/hartzellprop.com\/wp-content\/uploads\/unnamed-16-300x188.jpg 300w, https:\/\/hartzellprop.com\/wp-content\/uploads\/unnamed-16-768x481.jpg 768w, https:\/\/hartzellprop.com\/wp-content\/uploads\/unnamed-16.jpg 1200w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n\n\n<p>BETA has been flying its ALIA CTOL and ALIA VTOL aircraft with Hartzell\u2019s propellers for more than four years \u2014&nbsp;including completing the industry\u2019s first crewed transition of an eVTOL, and several long-range flights with its fixed-wing, including a coast-to-coast trip across the U.S., and now a Grand Tour of Europe.<\/p>\n\n\n\n<p>This relationship brought Hartzell\u2019s decades of expertise in propeller design and certification together with BETA\u2019s technology-centric, bleeding-edge approach. As the AAM sector continues to evolve, Hartzell Propeller and BETA Technologies set a precedent for how legacy aerospace expertise and next-generation innovation can come together to deliver safe, certified, and sustainable flight solutions.<\/p>\n<p><strong>About Hartzell Propeller<\/strong><\/p>\n<p>Hartzell Propeller, a Signia Aerospace company, is the global leader in advanced aircraft propeller design and manufacturing.
